Correlation between potential radiation-induced carcinogenic risks associated with WWER-1000 spent nuclear fuel and BREST-1200 radiation waste in case of annual generation of 1 GW of electricity. Part 2. Radiological migration equivalence

Currently it is acknowledged that the problem of disposal radioactive waste (RW) from nu-clear reactors largely depends on use fast neutron (fast reactors) in nuclear power industry. These are able to burn and transmutate long-lived radionuclides closed fuel cycle (NFC). In an open NFC with thermal (thermal reactors), unpro-cessed spent (SNF) buried. a reprocessed SNF disposed. this paper, feasibility possibility closing two-component industry studied. Potential biological hazard (PBH) public unprocessed reactor WWER-1000 re-processed BR-1200, were evaluated account relevant radionu-clides migration deep earth surface. PBH values expressed terms committed effective dose lifetime attributable risk (LAR) malignant neoplasms, normalized 1 GW generated electricity. RW BR-1200 about 100 times lower than WWER-1000. Comparative evaluation demonstrated doses dwell-water used by time appearance at surface 0.7 µSv 80 µSv/year respectively, LAR 6∙10-9 7.74∙10-6 re-spectively. At same time, WWER-1000, radio-nuclides earth’s order less BR-1200. accordance principle radiological equivalence disposal, was established satisfies limit for achievement equality equivalent mass uranium raw material will be within range 300 years. If ex-pressed achieved even earlier. Thus, when reprocessing operating simultaneous construction operation (in industry), ad-visable dispose RW, considering radiation-migration equivalence.
